Homeland Security Secretary Janet Napolitano claims these X-ray machines are “safe”? NO amount of X-rays penetrating your body’s cellular structure is “safe”. There are medical risks associated with ALL types of radiation, by the way, whether it penetrates or bounces off of your body… period. So Janet Napalitano and her agency of people-who-will-do-anything-just-to-keep-their-job are now essentially practicing medicine without a license, in my humble opinion.
